CLASP FOR SANITARY BELTS.

Application led September 15, 1923. Serial No. 662,901.

To all whom t may con-cem.'

Be it known that l, EDGAR M. GRUEN, a citizen ot the United States, andresident of the borough of the Bronx, in the county of Bronx, city andState of New York, have invented certain new and useful Improvements inClasps for Sanitary Belts7 of which the 'following is a specification.

.The main object of this invention is to provide an etlective clasp otsimple con-- struction readily operable to clasp the reduced end of asanitary pad or napkin.

A further object of the invention is to provide a claspv that may bequickly operf atedto release the pad by an outward pull on the end ofthe pad.

A clasp constructed in accordance with this invention while especiallyadapted for the use herein indicated., may be used for many purposes,for instance, as a garment supporter and for other like uses. l

The invention is designed particularly for use with the well known KoteXpads, but of course, it is lcapable of use with any form of pad ornapkin having soit or reduced ends adapted to be grasped firmly fbetween the clasp members.

In the drawing:

Referring to the various parts by numerals, 1 designates the lowerportion of a belt of any desired form. To this belt is,

secured a i depending fabric tape 2' to the lewer` end of {whichkthe'clasp is' connected. 1The clas'piconsists of a body`A part 3 and atubular clamping slide 4 mounted on the body part and arranged to movelongitudinally up and down thereon.

The body part of the clasp is formed of a comparatively narrow plate ofsheet metal having a slot 5 near its upper end to receive the tape 2,said slot having a-lower contracted part 6 adapted to receive a look-.ing tongue formed on the upper endof the clamping slide, as will bedescribed hereinafter. .-1 suitable distance Jfrom itsflower or .treeend the plate 3 is formed with. a mouth 7 which is in the form of atransverse slot extending inwardly and trans-` versely ot the plate 3from the lefthand edge, as shown clearly in F`ig..3.Y This slotrseparates the clasp head 8 from the body ot' the plate'.` said headbeing connected to. the plate 3 by a resilient neck 9 at theright handedge of the plate, the inner edge olfA said neck forming the inner wallof the mouth?. @ne of the functionsl of thisv resilient neck is topermit the head to yield or flex laterally when the clamping slide isforced into or out of clamping position, as will be described. A portionof the .plate 3, along the upper margin of the mouth 7 is bent forwardlyto form a stop Harige 110, said iiange extending transversely of theplate 3. This flange is cut away and rounded at its outer or lett handcorner 11 to permit the clamping slide to swing later-v ally with thehead 3. The side .edges .of the head are formed with forwardly extendinglongitudinal flanges 12 and 13. The flange 13 extends alongthe outerorright hand edge of the neck 9 to strengthen the neck and prevent itbeing bent or deformed either forward or rearward. These flanges form achannel in which the material to be clamped may be conveniently arrangedand also serve as guides for the clamping slide. The upper edge olf thehead 8, which forms the lower margin of the mouth 7, is serrated ortoothed, as shown. to securely hold the: fabric clamped over the head.The head 8 is dished or bulged forwardly between the.

flanges l2 and 13 to forni thehollowor concave back part 14C and theconvex for:-.

ward side 15, said parts being curved bothi longitudinally as well as'transversely of the head. The convex forward-side of' thef. head isformed with transversely 'extending serrations in the form of4 sharpteeth .16 into which the fabric is forced y t y bytheirclarhjpif ingslide. It will be noted thatthe'teethand the flange 10 forma transversechannel 18 which the looking tongue of the clamping-slide will. restwhen the slide is in Clamping. position.

The clamping slide is open ended and A tubular and `slides.readilylongitudinally ol the plate 3 and over tlieflanges 12 and 13. tis et`'suflieientlength tosulistaiitially enclose saidflanges and the headThe upper edge ofthe forward wallof the slide isspiovided. with anupwardly extending loekingtongue 19'wliose free end is bent inwarfflly.toerigage aiidiide on the forward face of 'the plate 3' above the mouthT. The looking tongue V1 9 is adapted to ent-er the part-.16 otthefslot.5to hold .the slide in its V.released position. as shown in Figs. 3 ande.

As the tongue 1S) is forced over the ridge 17 the headwill be slightly twisted about the neck 9.

rl`he lotex pad or other vfabritI :irtiele` isreleased from the clasp bymoriug the Clamping slide up on the plate 3. This may he done readily bypulling outwardly on tlieends of the fabric, as illustrated iii Fig. 6..The outward pull of the fabi-ie results in an upward `thrust on theslide vl.
